To assure proper hydration of the cement, the basecoat plaster should be kept damp for at least 48 hours. After the basecoat has been allowed to dry at least 5 days, finish materials may be applied following manufacturer’s recommendations. Fiber reinforced Perlite cement plaster basecoats accept a wide variety of finishes such as cementitious color and texture coats, stucco, polymerized cementitious coatings, tile, or masonry veneer. Tests have shown that the basecoat exceeds required shear values for tile and veneer by 300-400%. Expanded Perlite aggregates can be manufactured to weigh from 40 kg/m3 to 240 kg/m3 making it especially suitable for a number of applications in the construction industry. In addition to cement plasters, Perlite aggregate may be used in a variety of insulating plasters, lightweight insulating concretes, masonry wall insulation, cryogenic insulation, floating floor applications, and in the manufacture of simulated stone and brick.
